Double Klondike Solitaire Rules & Strategy

Double Klondike Solitaire is exactly what it sounds like — Klondike played with two standard 52-card decks shuffled together. The bigger deck means a larger layout, more foundations to build, and a longer, more complex game. If standard Klondike feels too short, Double Klondike is the natural next step.

What is Double Klondike?

Double Klondike (also called "Double Patience" or "Centennial" in some traditions) uses two standard 52-card decks — 104 cards total. The game follows all standard Klondike rules but scales the layout proportionally: nine tableau columns instead of seven, and eight foundation piles (one per Ace, but since there are two decks, there are two copies of each Ace).

Setup and Layout

Shuffling

Shuffle both 52-card decks together thoroughly. Riffle-shuffling a 104-card deck requires extra care — split it into thirds or shuffle each deck separately, then interleave them for a more practical approach.

Dealing the tableau

Deal 9 tableau columns. The first column receives 1 face-down card. The second receives 2 (1 face-down, 1 face-up). Continue this pattern through column 9, which receives 9 cards (8 face-down, 1 face-up). The top card of each column is always face-up.

The stock and waste

The remaining 59 cards form the stock (face-down). Draw from the stock to the waste pile as in standard Klondike. Most Double Klondike games use Turn 1 (draw one at a time) — Turn 3 is playable but rarely used since the game is already long.

The foundations

Eight foundation piles sit above the tableau — two for each suit (♠ ♥ ♦ ♣ × 2). Each foundation is built up from Ace to King in the same suit. Since there are two Aces of each suit, each Ace gets its own foundation.

Rules of Play

The rules follow standard Klondike with no exceptions:

• Tableau builds: Build down in alternating colors. A red 9 can be placed on a black 10. A face-down card is flipped face-up when it becomes the top card of a column.
• Moving runs: Any face-up sequence of cards in alternating-color order can be moved together as a unit to another tableau column.
• Empty columns: Only Kings (or runs starting with Kings) may be placed in an empty tableau column.
• Foundation builds: Move any Ace to a foundation, then build up from 2 to King in the same suit. Cards move to the foundation one at a time.
• Stock draw: Draw one card at a time (Turn 1) from the stock to the waste. The top card of the waste is always playable.
• Redeals: Typically one redeal is allowed — flip the waste pile back over and draw again. Some rule sets allow unlimited redeals; check your specific implementation.

How It Differs from Standard Klondike

Longer play time

A standard Klondike game takes 5–15 minutes. Double Klondike typically takes 20–45 minutes. The 9-column tableau with up to 9 cards per column creates significantly more buried cards to uncover.

More choices — but more blocking

Having two copies of every card sounds like it should make the game easier. In practice, it creates more blocking situations: a buried King might have a duplicate King blocking a crucial sequence elsewhere. The abundance of options can paradoxically lead to more dead ends.

Harder to get empty columns

In standard Klondike, clearing a 7-card column is ambitious but achievable early. In Double Klondike, clearing a 9-card column requires moving 8 buried face-down cards — a substantial undertaking. Empty columns are rare and precious.

8 foundations vs. 4

You win by filling all 8 foundations (104 cards total moved to foundations). This doubles the win condition compared to standard Klondike, making each individual foundation completion feel like a milestone rather than the final push.

Think of Double Klondike as "Klondike as a project" rather than "Klondike as a quick game." It rewards patience and planning far more than the standard variant.

Strategy Tips

Prioritize uncovering face-down cards

With 36 face-down cards in the initial deal (vs. 21 in standard Klondike), revealing hidden cards is even more critical. Every face-down card you turn over increases your options. Don't move visible sequences around unnecessarily when you could be uncovering new cards instead.

Manage duplicates carefully

When you have two copies of the same card, don't move both to the foundation simultaneously unless you have to. Keeping one copy in the tableau as a potential base for a sequence often serves you better than completing both foundations early.

Empty columns are gold

The same principle as standard Klondike, amplified. An empty column in Double Klondike is exceptionally powerful because the 9-column layout means longer runs can be temporarily staged there. Plan specifically toward creating empty columns rather than treating them as accidental byproducts of good play.

Don't rush Aces to the foundation

A classic beginner mistake in all Klondike variants, amplified in Double Klondike. Moving both copies of an Ace to the foundation as soon as you see them reduces your tableau flexibility. If a 2 or 3 of that suit is accessible and useful as a tableau card, keeping one Ace in play can be strategically correct.

Win Rate and Difficulty

Double Klondike is harder than standard Klondike Turn 1. The deeper face-down stacks and more complex blocking create more dead-end positions. Skilled players report win rates of 30–40%; casual players typically see 15–25%.
